The brake lights will not work when the pedal is depressed. They will work when trailer break is used. Help
The brake lights work when the trailer brake is used. Wont work when break pedal is depressed. I look at the switch on the break pedal it is working fine. Looked at all fuses and relays. Not sure where to look. Some of the one line complaints reference something on the steering column. There is a relay from the brake to the steering column that will not allow you to take the truck out of park if the break is not depressed. It also seems to be working fine.
